WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 404,393, dated June 4,1889.

Application filed March 6, 1889. Serial No. 302,107. (No model.)

To all whom it may concern:

Be it known that I, ALBERT ELMENDORF, a citizen of the United States,and a resident of New London, county of New London, and State ofConnecticut, have invented a new and useful Improvement in \Vater-Closets, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, making part of thisspecification.

My invention relates to an improvement upon the flushing andbowl-ventilating arrangement upon which Letters Patent were granted tome on the 3d day of July, 1888, No. 385,409, in which a flushingstand-pipe was employed in connection with a ventilating-ex tension ofsaid pipe and a ventilating-pipe connecting the bowl. and said extensionfor drawing off the gases and foul air from the bowl in the process offlushing thelatter; and my present improvement consists in connectingthe valve through which the flushing of the bowl is eifected with avalve in the ventilating-extension of the stand-pipe at a point abovethe connection of the bowl-ventilating pipe with said extension in suchmanner that when the valve for flushing the bowl is opened for thatpurpose the ventilating-extension of the stand-pipe will be closed,thereby compelling the air and gases for supplying the vacuum in thestand-pipe caused by the fallin get the column of water therein to bedrawn from the bowl through the ventilatin g-connection of'the bowl withthe stand-pipe.

It further consists in a novel construction of the valve connecting thesupply-pipe and the bowl with the flushing stand-pipe and in certaindetails of arrangement of the parts, hereinafter described and claimed.

In the accompanying drawings, Figure 1 tilating-extension of thestand-pipe and its valve.

A indicates the bowl and A the casing and seat therefor, which parts maybe of any usual or preferred form.

1) indicates the flushing stand-pipe; C and C, a ventilating-extensionthereof, the latter extending to or connecting with a flue and thencewith the open air; D, a valve-chamber connecting at its upper endthrough a pipe at with the lower end of the stand-pipe and at its lowerend with the water-supply pipe a. The stand-pipe B is similar to thatdescribed in the Letters Patent above referred to, and is provided atits upper end with a float-valve for closing said end when saidstand-pipe is full, as described in said patent. The construction of thesupply and flushing valve is shown in Fig. 3.

The valve-chamber D consists of a short section of pipeenlarged toaccommodate th e valve E, and provided with an inner tube D extendingupward from its lower end and terminating in a perforated diaphragm Dhaving annular ribs (Z d on its upper face forming the valve-seat. Thevalve is recessed 011 its lower face to receive a packing-ring c, whichrests, in the normal position of the valve, on the annular ribs (1 andcl, covering the space and the openings (1 between them, said openingscommunicating with the space around the inner tube D and connecting saidspace with the chamber above the diaphragm D The valve has a centralring at e to receive the valvestem E, which extends down through thetube D and through central guiding perforations in diaphragmsf and ftherein, and is provided with a conical valve F, of rubber or othersuitable material, secured to its lower threaded end by a nut E saidvalve F serving, when the valve E and stem E are raised, to close thelower end of the tube D and prevent the water from the supply-pipe fromrising therein.

The valve E has perforations or slots 6 around the ring 6, connectingthe tube D with the space in the valve-chamber above the valve E, andthe diaphragms f f have similar perforations f around their centralguidingnrings, which permit the passage of the water up around thevalve-stein and through the valve E into the valve chamber, whence itpasses into the stand-pipe connected therewith, preferably through ashort pipe (0, as stated. The valve F is inclosed in a chamber F in theupper enlarged end of a short coupling-section of pipe a which screws onthe lower end of the valve-chamber section D, as shown, and has thesupply-pipe a secured to its lower end in any usual manner.

a indicates the short section of pipe which connects the valve-chamber Dwith the standpipe 13, and which is preferably secured to thevalve-section of pipe by means of a threaded nut or collar 3 engaging anannular flange on the pipe a and the screw-threaded upper end of thevalve-chamber section 1), as shown; but any suitable form of couplingmay be employed for uniting the parts.

D is the flushing lateral branch or tube, which at its inner endconnects with the portion of the valve-chamber around the tube D andbelow the va1ve-seat or diaphragm, and which at its outer end isconnected with the bowl A in any usual manner for flushing it.

It will be seen. from the foregoing description that when the valve E isseated on the annular ribs (Z and d the water from the supply-pipe a canpass up freely around the valvestem E and through the valve E forfilling the standpipe, and that no water can escape through the openingsbetween said ribs into the branch D for flushing the bowl, and that whenthe valve E is raised it lifts the valve F through the stem E, therebyclosing the tube I) and cutting off the water-supply, while at the sametime the water above the diaphragm E and in the stand-pipe can escapefreely bet-ween the ribs 6 and 6 into the space below the diaphragm D'and thence through the pipe D into the bowl for flushing the latter.

The upper end of the stem E, projecting through the valve E, isscrew-threaded to engage a threaded perforation in the lower end orcross-bar of a loop or open link 1, which is provided on the inner faceof one of its upright bars with teeth g, forming a rack, with which theteeth h of a pinion or segment h on a rock-shaft ll engage for operatingthe valves E and F. The shaft H is journaled in suitable bearings in theside walls of the valve section or chamber D, and one end thereof,projecting through its supporting-wall, has a lever 7L2 fast upon it,made, preferably, in bellcrank form, and to one arm of which a spring 4has one end connected, the other end of said spring being connected to asuitable fixed sup port, with the spring arranged to exert its tensionto close the valve E and open the valve F.

0 indicates a section of the ventilating-extension of the stand-pipe 13,connected to the upper end of the latter, (just above the floatvalvereferred to,) and to which the upper end of the bowl-ventilating pipe I)is connected, the lower end of said pipe connecting with the bowl fordrawing off the foul air and gases in a manner described in the formerpatent referred to.

At a point above the connection of the pipe Z) therewith the section 0(see Fig. 4) is provided with an inclined partition or diapliiragm J,having a large central opening J, and underneath said diaphragm islocated a valve K, connected through a stem 7a with a rockshaft L,journaled in bearings in the side wall of said section, near the upperend of the diaphragm, and having a bell'crank lever L fast on itsprojecting end. The lower face of the diaphragm J has a suitablevalve-seat formed in or upon it, and the upper side of the valve isprovided with a packing-disk K, of any suitable material, snugly fittingthe valve seat for closing the opening J. One arm of the lever Lconnected by a cord or chain on with the lever 7L2, and has a pull cordor.

chain on connected to its other arm, the arran gement being such thatwhen the cord m is pulled, depressing the arm Z of the lever L, theshaft L will be rocked to close the valve K, and the arm Z, to which thechain m is attached, will be raised, lifting the valves E and F, throughthe connections described, for flu shing the bowl and cutting off thewater-supply. By this operation the supply of air from theventilating-extension C will be cut off and the supply of air necessaryto replace the falling column of waterwill be drawn through thebowl-ventilatii1g pipe I) from the bowl, thereby drawing elf the foulair and gases from the latter. \Vhen the pull cord orchain m isreleased, the spring t' operates to close the valve E and open the valveF, and at the same time, through the cord m and lever L, to open thevalve K, so that as the stand-pipe fills, the air and gases above thewater in the stand-pipe are forced up through the ventilatingextension0, and thence, through a suitable fine or otherwise, out into the openair.

The relative size of the ventilating-extension of the stand-pipe and theventilatingpipe connecting the bowl with said extension, and the naturaltendency of the foul air and gases to rise, causes said air and gases toflow out naturally through the freer upward vent allorded by theventilating-extension, when the valve in the latter is open, and enablesme to dispense with the valve in the bowlventilating pipe described inmy former patent above referred to. A further advantage in dispensingwith said valve and leavingthe bowl-ventilating pipe open lies in. thefact that if, from any cause, there should be leakage in the valve forclosing the stand-pipe when the latter is filled, the water so escapingfrom the stand-pipe will flow down through the bowlventilating pipe tothe bowl and waste-pipe, and so all danger of flooding or damage fromsuch leakage is effectually avoided.

N indicates a bracket for the attaclunent ot' the stand-pipe to the wallor other support,

and P a man-hole in the section 0 for giving access to the valve K forrepairs or other purpose.

Having now described my invention, I claim as new 1. The combination,with the bowl and its flushing stand-pipe, of the ventilating-extensionof said pipe, the ventilating-pipe conn ecting said bowl andventilating-extension, the flushing-valve, and the valve in theventilating-extension connected to the flushing-valve to be operatedsimultaneously therewith,substantially as described.

2. The combination, with the stand-pipe and bowl and the flushing-valveconnecting said pipe and bowl, of the ventilating-extension of saidstand-pipe provided with a valve connected to said fiushing-valve, andaventilating-pipe connecting said bowl with the ventilating-extension ofsaid stand-pipe, substantially as described.

3. The combination,with the bowl and stan dpipe, of the interposedvalve-chamber having the perforated diaphragm D and inner tube D, andthe connected valves E and F, arranged and operating substantially asdescribed.

i. The combination, with the bowl A and its flushing stand-pipe B, ofthe interposed valve-chamber or section of the stand-pipe having theperforated diaphragm and the lateral flushing-pipe D below saiddiaphragm, the lift-valve E, the water-supply valve F, connected to saidlift-valve to operate as described, and the rock-shaft connected to saidvalves for operating them, substantially as described.

5. The con1bination,with the bowl in a flushing arrangement forwater-closets, of the flushing-valve E, the ventilating extension orpipe 0 0', provided with a valve K, the ventilating-pipe 1), connectingthe bowl with the ventilating-extension pipe, and connections,substantially as described, for simultaneously operating the valves Eand K, for the purpose specified.

In testimony whereof I have hereunto set my hand this 4th day of March,A. D. 1889.

CHARLES PRENTI's, S. A. GARDNER.
